How Much Recycled Concrete Aggregate for a 16x100 Driveway?

A 16 by 100 foot driveway is 1,600 square feet. How much recycled concrete aggregate for a 16x100 driveway depends on depth: at 4 inches it is about 19.75 cubic yards or 25.7 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.

The math for a 16x100 driveway

Area: 16 × 100 = 1,600 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 1,600 × 0.333 = 533.3 cu ft.
Cubic yards: ÷ 27 = 19.75 yd³.
Tons: × 1.3 = 25.7 tons.

About recycled concrete aggregate

Ask whether the recycled concrete has been screened for rebar and debris. Fresh-crushed concrete can also be alkaline, so keep it away from sensitive plantings and streams. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. This driveway sees car and truck traffic, so match the depth to that load rather than to the minimum.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 28.2 tons may take more than one typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the driveway as firm ground allows.

When to choose recycled concrete aggregate

Good uses:

Driveway and pad bases
Temporary construction entrances
Fill under slabs when compacted in lifts

Poor fit for:

Near ponds, streams or sensitive plants, since fresh crush can raise pH
Decorative top layers
Drainage layers, unless the product is clean and screened

Quick reference numbers

Per inch over 100 sq ft: about 0.40 tons of recycled concrete aggregate (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.0 tons.
Another size for comparison: a 14x28 area at 2 inches takes about 3.1 tons.
Weight used here: about 1.3 tons per cubic yard.

Mistakes that throw off the order

Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
